Two things here:

First, "verneed" sounds like an ELF version problem. That is, there's 
something *else* that is the problem with your build, not the max-page thing. 
My guess is that you compiled against a newer version of Android's base 
libraries (Bionic) and you're running against an older one. Either that or the 
dynamic linker is producing a nonsensical error message. In fact, since it's 
printing "" and "_STORE_set_lookup_certs" instead of 
"X509_STORE_set_lookup_certs", I'm going to guess that you *do* have a broken 
dynamic linker, it has got lost and is corrupted, and thus produced a garbage 
error message.

Second, this is x86-64. There is no other page size besides 4 kB. I mean, huge 
pages (2 MB) and gigantic pages (1 GB) do exist, but I don't believe that's 
what the option is for. Maybe try passing the option only for your AArch64 
builds.
